Description
AC Infinity UIS Controller AI+ (CTR89Q) – take full control of your grow room.
The most advanced 8-port environmental controller AC Infinity build, designed for indoor growers. Built-in WiFi, Bluetooth and a clear touchscreen, so precise climate control sits in your pocket as well as on the tent pole.
Whether you are dialling in airflow, humidity or lighting schedules, the AI+ gives you command over every UIS-compatible device in the room.
Want CO2 control as well?
This is the controller on its own. The Controller AI+ with CO2 Sensor (CTR89A) is the same unit supplied with the CO2 sensor, so your fresh air exchange runs off real ppm readings instead of a timer. Worth it if you are sealed or supplementing CO2. You can also add a sensor to this one later.
Key features
- 8-port powerhouse – control up to eight devices from one hub: fans, lights, pumps and more.
- WiFi and Bluetooth – adjust settings remotely through the AC Infinity app.
- Smart touchscreen – 4" screen showing live data, timers, graphs and alerts.
- Automated climate triggers – sync devices to temperature, humidity, VPD or time of day.
- Data logging and alerts – charts and notifications, so heat spikes and power issues surface early.
- Plug and play with the UIS ecosystem – works with Cloudline fans, IonFrame LEDs and the Controller sensors.
- Password lock – stops accidental changes and tampering.
- UK and Europe – supplied with a UK plug, fully CE compliant.
Who it is for
Anyone running multiple AC Infinity devices, from a single 4x4 tent to a multi-zone room. If you want pro-level automation, detailed environmental control and remote monitoring, this is the controller.
